IPC: F16G3/00
Filed: 1933-04-28
Abstract: 412,384. Belt - fasteners. DOLEMAN, T., Mansfield Road, Clipstone, near Mansfield, Nottinghamshire. April 28, 1933, Nos. 12389 and 17342. [Class 80 (i).] Relates to a fixture for attaching belt-fasteners of the kind comprising two parts, each comprising a bent plate 17<a>, 17b, Figs. 1 and 2, pierced with rivet-holes and adapted to embrace a belt-end 12 and project to form spaced sockets 19, which mesh together to receive a hinge-pin. According to the invention, the fixture (i) holds, or assists in holding, the fastener in position while driving the rivets through the fastener and the belt end, Fig. 2 ; (ii) acts as a hollow punch or die for receiving the rivet ends ; and (iii) forms a support for the rivet heads while the projecting ends of the rivets are hammered over, Fig. 4. Holes 16, Fig. 2, registering with the rivet-holes in the fastener, are formed in the recessed portion 11<a> of the body 11 of the fixture to receive the rivet ends. The fastener is held in position against an upstanding rib 15 by a dummy hinge-pin 20 passing through lugs 13 on the fixture, and is positioned axially of the pin by stops 11<c>. In the modification shown in Fig. 7, the lugs 13 are formed by a bent metal strip screwed to the base, and the stop comprises an anglepiece 24 adjustable by a screw 25 and slot 26 along the recess 11<a>. During the clinching operation, the belt end is turned over and held by passing the dummy hinge-pin 20 through lugs 22 on the fixture 11. In a further modification, not shown, the recess 11<a> is replaced by a raised plate. Also, in this form the rib 15 may be omitted, and the raised plate extended on the other side of the lugs 13 so that the belt end can be swung 180‹ about the pin 20 from the position shown in Fig. 2 into the clinching position. In a further modification, the depression 11<a> slopes down towards the lugs 13 and the rib 15 is extended vertically and chamfered so that it can be used for forcing apart the legs 17<a>, 17b of the fastener. The horizontal edge of the fixture also may be chamfered. According to the Provisional Specifications, slots may be used instead of the holes 16.

Title: Process for the production of alcohols
IPC: C07C29/04
Filed: 1956-04-24
Abstract: Alcohols are produced by the hydration of olefines at elevated temperature and pressure in the gaseous phase and in the presence of a catalyst, the catalyst being a silico-phosphoric acid or a salt thereof.  The salts of silico-phosphoric acid are prepared by adding to a freshly precipitated silica gel the calculated amount of phosphoric acid and introducing the corresponding metal hydroxide. In the examples: (a) ethylene is treated with steam in the presence of a catalyst consisting of the aluminium salt of the silico-phosphoric acid SiH2(PO4)2 to give ethyl alcohol; (b) ethylene is treated with steam in the presence of a catalyst, formed by mixing aluminium hydroxide gel with silica gel and treating the mixture with phosphoric acid, to give ethyl alcohol; and (c) ethylene is treated with steam in the presence of a catalyst of formula AgHSi(PO4)2 to give ethyl alcohol.  Also mentioned as catalysts are the divalent cerium salt of H2Si(PO4)2 and the ferrous salt of H2Si(PO4)2.  U.S.A. Specification 2,579,601 is referred to.

Title: Improvements in and relating to the production of artificial finger and toe nails
IPC: B29C39/00
Filed: 1963-03-29
Abstract: Artificial finger or toe nails are formed directly on the natural nail by applying a solution of a polymer in a monomer, or in an inert solvent, and then either polymerizing it in position or allowing the solvent to evaporate, so as to leave an adherent film which can be trimmed as desired.  The portion beyond the end of the natural nail is formed by moulding the film in a template which is subsequently removed.  The mixture applied is preferably polymethyl methacrylate in monomeric methacrylic acid methyl ester and this may be applied either directly as a mass of dough-like consistency or as a thin sheet, the adhesion of which may be assisted by the interposition of a priming layer comprising, for example, polyvinyl chloride, polyvinyl alcohol or halogenated synthetic rubber.  In each case the setting time may be up to eight minutes.ALSO:Artificial finger or toe nails are formed on the natural nail by applying a solution of a polymer in a monomer, or in an inert solvent, and then either polymerizing it in position or allowing the solvent to evaporate, so as to leave an adherent film which can be trimmed as desired.

Title: Improvements in resilient suspension means for vehicles
IPC: B62K25/08
Filed: 1947-05-10
Abstract: 631,834. Vehicle suspensions; shockabsorbers. DUNLOP RUBBER CO., Ltd., and SEDDON, R. M. May 10, 1947, No. 12696. [Classes 108 (ii) and 108 (iii)] [Also in Group XXXI] In a resilient suspension means adapted to act in compression, two coaxial tubular resilient members 61, 61a contained within two telescopic members 45, 50 surround interengaging guide members 57, 58, while a piston 62 is disposed between the adjacent ends of the resilient members to form two chambers of variable volume; air can flow relatively freely from one of these chambers, but its return thereto is restricted. The tubes 45, 50 are respectively closed by plugs 46, 53, to which are attached the guide means 57, 58, a sliding bush 59 serving as an abutment ' for the resilient column 61. To prevent contact between the guide members and the resilient columns, which are formed of rubber or like resilient material, the former may be surrounded by a helical spring 68, or the bore of each disc comprising the column may be made tub-shaped. The abutting ends of the columns 61, 61a hold between them the piston comprising a cupwasher 64, in the crown of which is a small hole 65. On compression, air can escape freely from the upper tube 45 past this washer and pass to atmosphere through a hole 66 in the lower tube. Rebound is, however, damped as air can only return to the tube 45, through the small hole 65. Two opposed cup-washers may be used, in which case a valve is provided in the wall of the tube 45 to control air flow. The damping effect may be va ried by making this valve adjustable, or by placing the piston washer nearer one end of the telescoping members. Where, as in the case of a motor cycle front fork, two elements are connected in parallel relationship by transverse tubes 41, 42, holes coinciding with opposite ends of one of the bridging tubes may be drilled in the walls of the sleeves 45 and a single valve be provided, either on the tube or the wall of a sleeve 45, to control air flow in both elements. The rubber discs may be reinforced by bonding metal or fabric elements to their end faces; or they may be replaced by a single, or a set of, cylindrical tubes. The guide means may comprise a rod and tube, as shown, or inter-engaging slotted members. The spring may be of streamline shape in cross-section, and. if an elliptical shape is used, a set of guide members is provided at each focus.

Title: Improvements in or relating to Aircraft Gun Mountings.
IPC: F41A27/30
Filed: 1917-09-08
Abstract: 128,980. Vickers, Ltd., and Savage, H. A. Sept. 8, 1917. Mountings for use on aircraft.-Relates to aircraft gun mountings having a clutch device for holding the gun in elevation, which is declutched on grasping the elevating hand-grip, and clutched again by means of a spring when the hand-grip is released. According to the invention, the spring of the clutch also acts to balance the turning-moment on the gun due to air pressure. Fig. 1 shows the invention applied to a Lewis gun A mounted in a bracket a moving, during elevation, on a trunnion pin C<2> fixed to brackets C' on the rear spar C of the upper wing of an aeroplane. A lever D' I forming part of the hand-grip A' is connected by a rod d<1> and arm d to a spring- controlled friction clutch shown in detail in Fig. 3. The fixed element B of the clutch is integral with the pin C<2>, and the moving element B' is carried by a sleeve b, which can slide on the pin C<2> so as to compress a spring B<2> and disengage the clutch. The sliding movement of the sleeve is effected when the lever D<1> and hand-grip A' are grasped, by inter-engaging inclines d<x> on the lever d and sleeve b. The spring B<2>, the ends of which are fixed to the sleeve b and a collar c fast with the pin C<2>, also acts by torsion to balance the turning-moment due to air pressure acting on the forward part of the gun.
Patent GB-401676-A (GB)
Title: Improvements in and relating to the union of cupriferous metals with ferrous metals
IPC: B32B15/01
Filed: 1932-05-05
Abstract: To effect a strong union between ferrous metal and cupriferous metal the metals are brought into intimate contact and heated so that solid diffusion takes place, the temperature and time being so controlled that the amount of copper from the cupriferous metal which diffuses into the ferrous metal does not exceed at any point the solubility of copper in iron at the point at which the a -g  transformation begins. The temperature may be kept below the a -g  transformation point or may be equal to or above this point, the time of heating being controlled in the latter case to prevent excess diffusion of the copper.  The time of heating is also preferably controlled so that the copper is not unduly contaminated by diffusion of iron.  The metals may be placed in contact and rolled or pressed during heating, or the cupriferous metal may be electrolytically deposited on the ferrous metal and the coated metal, preferably after the density of the coating has been increased by rolling, heated under the conditions set out above to produce a firmly adhering and non-porous coating.  The heating is preferably carried out in a neutral or reducing atmosphere, e.g., illuminating gas, hydrogen or carbon monoxide. Examples given describe the heating of copper-coated low carbon steel for 10 hours at 760 DEG  C which is below the a -g transformation point of 810 DEG  C, or for 1/2 hour at 927 DEG  C. The metal is then cooled, preferably rapidly, so that the copper remains in solid solution or is precipitated only in a very finely divided state.  The ferrous metal may be iron, steels with varying carbon contents, or alloy steels containing for example nickel, chromium, manganese, or vanadium, and the cupriferous metal may be copper, or copper alloys such as brass, bronze, or cupro-nickel. Sheets, plates, wires, strips, billets, etc., of ferrous metal covered wholly or in part with a casing of cupriferous metal, or coated shaped articles such as machine elements, shafts, &c. may be made by the process described.

Title: Improvements in high frequency signalling systems
IPC: H01Q21/06
Filed: 1934-04-30
Abstract: 442,003. Directive wireless systems. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. April 30, 1934, No. 12988. Convention date, April 29, 1933. Drawings to Specification. [Class 40 (v)] In a high frequency transmitting system comprising an aerial fed by a transmission line, the constants of the aerial are so proportioned in respect of the frequency used that the phase angle between current and voltage in the aerial equals the electrical length of the transmission line. The Specification contains a mathematical discussion of the problem of maintaining aerial current constant in phase and amplitude under variations of aerial capacity due to weather conditions and shows that this is the case with the above specified phase relationship if the attenuation of the line is neglected. If attenuation is taken into account, aerial current variations are at a minimum with the specified phase relations. This question is of importance in multiple aerial beacons giving directional transmission, and any desired relative phase displacements between the aerials is obtained by the use of artificial lines in the transmission lines leading to the various aerials.
Patent GB-422027-A (GB)
Title: Improvements in or relating to processes for manufacturing artificial or reconstructed leather
IPC: C08L89/06
Filed: 1934-05-01
Abstract: A process employing felting operations for making artificial leather from mixtures of disintegrated scraps and cuttings of leather or hides or both and rubber latex is characterized in that the mixtures employed contain one or more of the oxides and hydroxides of metals and metalloids belonging to groups higher than Group II of the Periodic Classification of the Elements. Oxides and hydroxides of aluminium, silicon and titanium, and oxides of vanadium, iron and nickel may be used.  The oxides &c. may be added as such or produced by precipitation in situ in an aqueous dispersion of disintegrated scraps, or may be mixed with oils and ground into the mixture of rubber latex and fibre.  About 5-15 per cent of oxides &c. are used, calculated on the dry disintegrated cuttings.  The cuttings may be tanned or untanned. In an example, 230 kg. of chrome tanned hide cuttings are washed, neutralized and defibred in the presence of water.  A certain amount of vegetable fibres may then be added.  The tanned fibres are then partially detanned by adding 4 kg. Seignette's salt, 45 kg. chromine are incorporated, and a second tanning is carried out by adding 30 kg. of a chrome tanning agent, the acid produced being neutralized by sodium carbonate, and then 20 kg. of a vegetable tanning agent; the mass is then worked until complete tanning takes place.  At this stage 20 kg. titanium dioxide is added, either as such or produced in situ by adding ammonium hydroxide and titanium chloride, and dispersed in the mixture. Vulcanizing agents, accelerators, antiagers and dyestuffs are then added and the mixture is conveyed to containers or direct to the feeding channel of a paper-making machine where it is mixed with 170 kg. latex having 40 per cent dry rubber content, or the latex may be more dilute.  Just before the mixture reaches the wire net forming the endless conveyer of the paper-making machine a coagulating solution, e.g. of sodium chloride is added.  The latex may contain either sulphur or accelerator, but not both, to obviate risk of premature vulcanization.  Specifications 247,089, 315,413, [both in Class 70], and 365,564 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of rubber other than as latex. This subject-matter does not appear in the Specification as accepted.
